CHARLES F. T. KANDELER, OF CHICAGO, ILLINOIS.

FIREPROOF FLOOR AND CEILING CONSTRUCTION.

SIZECIFICATION forming part of Letters Patent No. 560,410, dated May 19, 1896.

Application filed February 26, 1896. $eria1 No. 580,921. (No model.)

To all whom, it may concern.-

Be it known that 1, CHARLES F. T. KANDE- LER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Fireproof Floor and Ceiling Construction,of which the followingis a spccification.

My invention relates to an improvement in the construction of buildings involving the framework formed throughout of metal beams and bars; and my object is to provide an economical and comparatively light floor and ceiling construction for such buildings.

Referring to the accompanying drawings, Figure 1 is a broken sectional plan view illustrating my improved floor and ceiling construction in its preferred details; Fig. 2, a section taken at the line 2 on Fig. 1, viewed in the direction of the arrow and enlarged; and Fig. 3, a section taken at the line 3 on Fig. 2 and viewed in the direction of the arrow.

A A denote the floor-beams, which are preferably I-beams. The joists are shown at B in their preferred form of channel-irons extending lengthwise at suitable intervals apart say three feet, more or lessbetween the I-beams, to the webs of which they are fastened at their opposite ends.

C C denote flat-metal floor-bars,the required thickness of which need not exceed one-eighth of an inch and which maybe about two inches wide. These bars are placed edgewise upon the joists B to extend transversely of the latter at, say, about eighteen inches, more or less, apart, and from them are suspended below the floor-beams to extend parallel with the bars C or in other desired direction the metal ceiling-strips D, suitable transverse dimensions for which are about three-fourths of an inch wide by one-eighth of an inch thick.

For suspending the ceiling-strips I provide the bars E, preferably in the form of angleirons, one adjacent to each joist, which it crosses, being riveted or bolted at the opposite ends of one wing, respectively, to a floorbar C and a ceiling-strip D, and preferably, though not necessarily, fastened intermediately through its other wing to a joist. Between the points of thus suspending the coiling-strips from the floor-bars I also reinforce the latter to brace them against overturning under the strain of the load upon them by means of the bars F, which are, preferably, also angle-irons, fastened at their opposite ends, respectively, to the floor-bars and the ceiling-strips between the suspension-bars E at intervals, say, of a foot, more or less. In this way I securethe advantage in economy of using light channel-iron joists with heavy floor-beams and a light and durable fireproof floor construction with a suspended ceiling structure by the use of the connected thinmetal floor-bars and ceiling-strips.

For the sake of eXpedition,con venience,and economy I prefer to provide my improved structure in sections, each composed of a number of the bars C, strips D, and their respective connecting-bars E E and F F, the series of floor-bars C in each section being connected together at their upper edges by metal laths G and having fastened upon them the wooden floor-strips I, and the series of ceiling-strips D being connected together at their lower edges by metal lath G. The floor-bars in each section are of a short length sufficient to reach across from one side of one joist to the opposite side of the next adjacent one, and the ceiling-strips in each section are of a length adapting them to extend lengthwise between and short of adjacent joists. Thus these sections maybe made up complete in the shop and transported to the building ready to be placed by inserting them in proper position between joists B with the bars C resting upon them and the ends of adjacent bars overlapping each other, as represented in Fig. 1, and fastening of the suspension-bars E to the joists may be done after the sections have been thus placed.

It is also within my invention to provide the sections in myimproved construction with the parts C, G, and I, put together in the shop,

and the parts D and G, separately .put together there, when these subsections may be placed and fastened together at the building by means of connecting-bars. Moreover, it is within my invention to formthe sections in the shop of the parts C, G, D, G, and E, ready to be placed in position in the building, as it is also within my invention to provide the sections each in its entirety in the shop and composed of the parts C, G, D, G, E, and

IOC

F, with or without the floor-strips I. As will be understood, when the sections have been placed on the joists B the concrete II may be applied to the covering G, flooring I may be placed on the wooden flooring-strips I, and plaster II for the ceiling may be applied to the wire lath G.

Wherever wire lath is mentioned in the foregoing description and in the appended claims I intend the expression to include any suitable sheeting as an equivalent of wire lath.

That I claim as new, and desire to secure by Letters Patent, is-- 1. In a fireproof floor construction, the combination of joists B, bars 0 extending across and resting on the joists, and bars E fastened to the bars 0 to depend therefrom and secured to parts of the structure below said bars 0, substantially as described.

2. In a fireproof floor construction, the combination of joists B, bars 0 extending across and resting on the joists, bars E fastened to the bars C to depend therefrom and secured to parts of the structure below said bars C, and a fireproof covering on said j oist-crossin g bars, substantially as described.

3. In a fireproof floorconstruction, the combination of joist-s B, bars 0 extending across and resting on the joists, bars E fastened to the bars 0 to depend therefrom and secured to parts of the structure below said bars 0, a fireproof covering on said j oist-crossing bars and a fireproof ceiling below the joists, substantially as described.

4. In a fireproof floor and ceiling construction, the combination of joists B, bars 0 extending across and resting on the joists, bars E fastened to the bars 0 to depend therefrom, and ceiling-strips D connected with said bars C by the bars E, substantially as and for the purpose set forth.

5. In a fireproof floor and ceiling construction, the combination with the floor-beams A, of joists B extending between the floor-beams, bars 0 extending across and resting on the joists, bars E fastened to the bars 0 to depend therefrom, and ceiling-strips D connected with said bars 0 by the bars E, substantially as and for the purpose set forth.

6. In a fireproof floor and ceiling construction, the combination with the floor-beams A,

of joists B extendingbetween the floor-beams, bars 0 extending across and resting on the joists, bars E fastened to the bars 0 to depend therefrom, ceiling-strips D connected with said bars 0 by the bars E, and bracing-bars F connecting said bars 0 and ceiling-strips, substantially as and for the purpose set forth.

7. In a fireproof floor and ceiling construction, the combination with the joists, of the sections each formed of bars C and strips D connected at intervals by the bars E and F, and carried by said joists to support the floor and ceiling, substantially as described.

8. A fireproof floor and ceiling construction formed in sections composed of floor-bars 0, wire lath G and floor-strips I, and the ceilingbars D and wire lath G connected with said floor-bars, substantially as described.

9. A section for a fireproof floor and ceiling construction, comprising the floor-bars 0, wire lath G and floor-strips I, substantially as and for the purpose set forth.

10. A section for a fireproof floor and ceiling construction, comprising the floor-bars C, wire lath G, ceiling-strips D, wire lath G and bars E connecting the floor-bars and ceilingstrips, substantially as and for the purpose set forth.

11. A section for a fireproof floor and ceiling construction, comprising the floor-bars 0, wire lath G, ceilin strips D, wire lath G, and bars E and F connecting the floor-bars and ceiling-strips, substantiallyas and for the purpose set forth.
